2 Warning It is your sole responsibility to install and use the instrument and transducer(s) in a manner that will not cause accidents, personal injury or property damage. Always observe safe boating practices. The choice, location, and installation of transducers and other components of the system are critical to the performance of the system as intended. If in doubt, consult your Simrad dealer. To reduce the risk of misusing or misinterpreting this instrument, you must read and understand all aspects of this Installation and Operation Manual. We also recommend that you practice all operations using the built-in simulator before using this instrument at sea. Global Positioning System: The Global Positioning System (GPS) is operated by the US Government which is solely responsible for its operation, accuracy and maintenance. The GPS is subject to changes which could affect the accuracy and performance of all GPS equipment anywhere in the world, including this instrument. Electronic Chart: The electronic chart used by this instrument is an aid to navigation designed to supplement, not replace, official government charts. Only official government charts supplemented by notices to mariners contain the information required for safe and prudent navigation. Always supplement the electronic information provided by this instrument with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further. AIS: The AIS features on this chart-plotter are designed as a safety aid only and do not guarantee safety at sea. AIS transmission is mandatory on some, but not all, vessels. You should check your local laws and regulations for requirements in your area. As a result of different legal requirements, different vessel sizes and uses, you should not assume that your AIS equipped chart-plotter will show the location of ALL vessels in your area. Careful prudence, judgement, and safe navigation practices should always be exercised. AIS should be used to complement radar, but AIS is not a substitute for radar. Sounder performance: The accuracy of the echosounder depth display can be affected by many factors, including the type and location of the transducer and water conditions. Never use this instrument to gauge depth or other conditions for swimming or diving. Fuel data: Do not rely on this instrument as the sole source of information about fuel available onboard. You must supplement this instrument s fuel data with visual or other checks of the fuel available. This is necessary because possible operator errors, such as forgetting to reset the fuel used when filling the tank or running the engine with this instrument not switched on, can render this instrument inaccurate. Fuel economy can change drastically depending on boat loading and sea conditions. Always carry adequate fuel onboard for the intended trip, plus a reserve to allow for unforeseen circumstances. Simulate mode: Never have simulate mode on when you are navigating on the water. Failure to adhere to these warnings may lead to death, serious injury or property damage. Simrad disclaims all liability for installation or use of this product that causes or contributes to death, injury or property damage or that violates any law. 2 Simrad NX40/45 Installation and Operation Manual

7 1 Overview 1-1 Overview The Simrad NX40/45 is a rugged, highly integrated marine chartplotter and fishfinder. It is easy to use and has a high resolution color display. Complex functions can be performed with only a few key presses, taking the hard work out of boating. The available functions depend on the optional sensors and instruments that are installed: The Video window requires the NX40/45 to receive video from a compatible source, such as a camera. Fuel functions require fuel sensors to be installed. SmartCraft engine functions require a SmartCraft system to be installed. For information on using SmartCraft, see the SmartCraft Gateway Installation and Operation Manual. The NX40/45 can send data to other instruments, such as an autopilot, and receive data from other instruments. Radar functions require an optional Simrad radar system to be installed. AIS functions require an optional AIS receiver to be installed. For information on installation options. This manual describes how to install and operate the NX40/45. Special terms are explained in Appendix C. For more information on this instrument and other Simrad products, go to our website, Cleaning and maintenance The screen is covered by a proprietary anti-reflection coating.

19 3 Navigation: Chart 3-1 Introduction to navigating The unit has two ways of navigating, going straight to a point or following a route Navigating to a point When the unit is navigating to a point, the chart and highway windows show navigation data: B A The boat position. B The destination point marked with a circle. C The boat s plotted course to the destination. A C D D D Two CDI lines, parallel to the boat s plotted course, which indicate the maximum expected deviation from the plotted course. For more information, see Appendix C. If the unit is connected to an autopilot, the unit will send data to the autopilot to steer the boat to the destination. Start the autopilot before starting to navigate to the point. If the unit has no autopilot, steer the boat manually. use the boat position and destination on the chart or highway windows; use navigation data shown on the data header or; use COG and BRG on the compass. Note: If the XTE alarm is enabled, an alarm will sound if the boat deviates too much from its intended course. If the arrival radius alarm is enabled, then an alarm will sound to show that the boat has reached the destination. When the destination is reached an arrival warning appears with the option to cancel navigation Going to a waypoint or to a point on the chart A waypoint is a position that you can set on the chart, for example a fishing spot or a point on a route.

35 8 Satellites GPS worldwide navigation The GPS system is 24 satellites orbiting the earth and broadcasting position and time signals. The GPS receiver analyses the signals from the closest satellites and calculates exactly where it is on earth. The accuracy is typically better than 10 m (33 ft) for 95% of the time. GPS receiver (Optional) Simrad GPS units have a sensitive 12 channel receiver, which tracks signals from all GPS satellites visible above the horizon and uses measurements from all satellites more than 5 above the horizon to calculate the position. Each time a GPS receiver is turned on, it normally takes about 50 seconds before it outputs the first position.

36 9 Echosounder fishfinding: Introduction! WARNING Use the automatic Cruising or Fishing modes when learning to use the unit or when travelling at speed. 9-1 Using the unit The unit uses a echosounder transducer attached to the hull. The transducer generates an ultrasonic pulse (sound that is above the hearing range of the human ear), which travels down towards the bottom at a speed of about 1463 m/s (4800 ft/s), spreading out into a cone shape. When the pulse meets an object, such as a fish or the bottom, it is partly reflected back up towards the boat as an echo. The depth of the object or bottom is calculated by the unit by measuring the time taken between sending a pulse and receiving the echo. When an echo has been returned, the next pulse is sent. The unit converts each echo into an electronic signal, shown as a vertical line of pixels. The most recent echo appears on the extreme right of the window, with the older echoes being scrolled towards the left, eventually disappearing off the window. The scroll speed depends upon the water depth and scroll speed setting. The appearance of echoes shown are affected by: The unit settings. Echoes (different fish types, different bottom types, wrecks and seaweed. Noise (water clarity and bubbles.) Cruise, Fishing and Manual Modes The unit has three echosounder operating modes: Cruising mode: Use this when on the move. The unit automatically adjusts its settings to compensate for water clarity and to display the bottom. Fishing mode: Use this when fishing. The unit automatically adjusts its settings to compensate for water clarity and to best display fish, the bottom and other details. Manual mode: Use this to fine-tune the unit settings by hand. Best results are often achieved in manual mode, but practice and experience are required to obtain the optimum settings for different conditions. 36 Simrad NX40/45 Installation and Operation Manual

37 9-2 Interpreting the display The echosounder windows do not show a fixed distance travelled by the boat; rather, they display a history, showing what has passed below the boat during a certain period of time. The history of the echosounder signal shown depends the depth of the water and the scroll speed setting. In shallow water, the echoes have a short distance to travel between the bottom and the boat. In deep water, the history moves across the window more slowly because the echoes take longer to travel between the bottom and the boat. For example, when the scroll speed is set to Fast, at depths over 1000 ft (300 m) it takes about 2 minutes for the data to move across the window, whereas at 20 ft (6 m) it takes only about 25 seconds. A School of fish B Single fish C Hard bottoms such as rock and coral show as wide bands D Soft bottoms such as mud, weed and sand show as narrow bands The scroll speed can be set by the user to display either a longer history with less fish information or a shorter history with more fish details. If the boat is anchored, the echoes all come from the same area of bottom. This produces a flat bottom trace on the window. The screen shot shows a typical echosounder window with the Fish symbols turned Off. The echosounder pulse generated by the unit transducer travels down through the water, spreading outwards in a cone shape. The cone width is dependent upon the frequency of the pulse; at 50 khz it is approximately 45, and at 200 khz it is approximately 11. The differences in the cone width affect what is shown. Strength of echoes The colors indicate differences in the strength of the echo. The strength varies with several factors, such as the: Size of the fish, school of fish or other object. Depth of the fish or object. Location of the fish or object. (The area covered by the ultrasonic pulse is a rough cone shape and the echoes are strongest in the middle.) A D C B Simrad NX40/45 Installation and Operation Manual 37

38 CAUTION Planing hulls at speed produce air bubbles and turbulent water that bombard the transducer. The resulting ultrasonic noise may be picked up by the transducer and obscure the real echoes. Clarity of water. Particles or air in the water reduce the strength of the echo. Composition or density of the object or bottom. Bottom types Mud, weed and sandy bottoms tend to weaken and scatter the echosounder pulse, resulting in a weak echo. Hard, rocky or coral bottoms reflect the pulse, resulting in a strong echo.

39 Shadows Shadows are created around areas where the ultrasonic beam cannot see. These areas include hollows on the bottom or beside rocks and ledges, where the strong echoes returned off the rocks obscure the weak echoes of the fish and may also create a double bottom trace. See following for an example of the echosounder window in such an environment. A double bottom trace is shown on the window. When looking for fish with the wide angled 50 khz frequency, be aware of increased shadows. Use the high frequency 200 khz in areas that have rocks and ledges because this frequency reduces the shadow effect considerably. A Fish is visible on the window B Fish is hidden by the strong echoes off the bottom and is not shown on the window 9-3 Single and Dual frequency fishfinding Sounder frequencies The unit has two echosounder frequencies, 200 khz and 50 khz.. Example of shadows A B A Sounder window of same area To select the echosounder frequency > Frequency > 200 khz or 50 khz or Mixed When to use 200 khz The 200 khz frequency is especially suitable for use in shallow and medium depth water, typically less than 500 ft (150 m) and while running at speed. At 200 khz, the narrow cone reduces any noise caused by air bubbles. The 200 khz frequency generates a higher definition pulse which produces little shadow and returns excellent detail over a small area of bottom. Therefore, it gives excellent bottom discrimination capability and is particularly good at showing individual fish, including bottom dwellers. When to use 50 khz The 50 khz frequency is particularly suitable for use in deep water, typically greater than 500 ft (150 m). At 50 khz, the cone covers an area of water about four times wider than the 200 khz cone and penetrates to a greater depth with minimal loss of the return signal. However, it produces a lower definition display with more shadow compared to the 200 khz frequency. This means that a group of small fish, for example, could be shown as a single item, while any fish very close to the bottom B A A Simrad NX40/45 Installation and Operation Manual 39

40 A B may not be found at all. This frequency is useful for getting a deep, wide overview of the area so that any areas of interest can be identified and then examined in detail with the 200 khz frequency. When to use Mixed The Mixed frequency combines the 200 khz and the 50 khz echoes on one echosounder window, filling in detailed echoes in the center of the echosounder cone. When to use 50/200 khz Operating the unit at both 50 khz and 200 khz simultaneously on a split window can be very useful when operating in shallow to medium water, typically less than 500 ft (150 m), because the 50 khz section of the window shows the general area, while the 200 khz section can be viewed simultaneously for a more detailed look at any interesting feature. To use 50/200 khz, select the Split 50/200 window. A Narrow angle, more detailed 200 khz cone B Wide angle, less detailed 50 khz cone 40 Simrad NX40/45 Installation and Operation Manual

42 9-4 Fish detection and display Where to find fish Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the 50 khz or 50/200 khz frequency window to find these features, then look for fish by passing over the feature slowly several times using the Zoom window. If there is a current, the fish will often be found downstream of the feature. A weak fuzzy band may appear between the bottom trace and surface. This might indicate a thermocline - a rapid change in water temperature, such as the edge of a warm or cold current. The temperature difference can form a barrier which the fish may not swim through. In fresh water, fish often collect around a thermocline. Fish arches In good conditions, a fish passing through the coneshaped ultrasonic pulse is shown as a fish arch. The 50 khz frequency uses a wider cone than the 200 khz frequency. This makes the fish arches easier to see. A fish arch starts when a fish enters the weak edge of the echosounder cone, generating a weak echo that is shown as the start of the fish arch. As the fish moves closer to the middle of the cone, the distance between the transducer and the fish reduces and the echo is shown at progressively shallower depths, producing a rising shape. When the fish passes directly beneath the middle of the cone, the echo becomes strongest and thickest. As the fish passes out of the middle of the cone the reverse happens with a progressively weaker and deeper echo. There are many reasons why fish arches may not be seen. For example: Poor transducer installation (see Transom Transducers Installation Guide). If the boat is anchored then fish will tend to show on the window as horizontal lines as they swim into and out of the transducer echosounder beam. Slow speeds in deeper water give the best fish arch returns. Range is important. It will be much easier to see fish arches when using zoom mode to concentrate on a particular section of water, rather than just showing everything from the surface to the bottom. Zooming increases screen resolution and is necessary for good fish arches. It is difficult to get fish arches in shallow water as the transducer echosounder beam is very narrow near the surface and fish do not stay within the beam long enough to show an arch. Several fish in shallow 42 Simrad NX40/45 Installation and Operation Manual

43 water tend to show as randomly stacked areas of color. Wave motion may result in distorted fish arches. 9-5 Range Range is the vertical depth shown on the unit echosounder window. For example, if the range is 100 m, then the echosounder window shows depths between 0 and 100 m. The range is shown at the bottom, right corner of a echosounder window. The unit has two range modes: Auto: The unit adjusts the range automatically so that the bottom of the water is always shown at the bottom of the window. Auto range is recommended for normal operation. To set Auto mode Go to a echosounder window > > Range > Auto Manual: The unit does not adjust the range automatically. If the bottom depth is below the range, the bottom will not appear on the window. Manual range is useful if the bottom depth changes rapidly, because Auto range will cause the window to change range frequently. To set Manual range or to change the range Go to a echosounder window > Zoom range and offset The echosounder Zoom and Bottom windows can show a magnified part of the range. 9-6 Gain and threshold Gain and threshold settings control the amount of detail shown on a echosounder window: Gain: The gain of the echosounder receiver. The gain should be high to display good detail, but if the gain is too high then information from the strong bottom signal is lost and false echoes might be shown. There is a separate gain setting for each echosounder frequency, 50 khz and 200 khz. Threshold: Return echoes less than the threshold are ignored. The threshold should be as low as possible, but if the threshold is too low, unwanted noise will be shown. Threshold is set as a percentage of gain. For example, if the threshold is 50 %, then return echoes less than 50 % of the maximum signal are ignored. There is a separate threshold setting for each echosounder frequency, 50 khz and 200 khz.! WARNING Use the Auto range when learning to use the unit or when travelling at speed. Simrad NX40/45 Installation and Operation Manual 43

48 Use the A-Scope while adjusting the gain and threshold settings manually. Setting gain and threshold It is convenient to use the A-scope window when adjusting gain and threshold manually. Follow this procedure to adjust gain and threshold for normal circumstances: Switch to a echosounder window. If necessary, press to adjust range so that the bottom is shown. If necessary, select the echosounder frequency to adjust the settings for. Press, select Frequency and select 200 khz or 50 khz. > Echosounder splits > Split A-scope. Press to display the Gain window. To adjust gain or threshold for a frequency, press up or down to select the setting to adjust, then press left or right to change the setting. Set threshold to zero. Adjust Gain so the peak of the strong signal from the bottom just touches the gain line. Adjust threshold so that it is just to the right of the noise. Press to close the gain window. If required, repeat these steps to adjust gain and threshold for the other frequency. Note: Setting the gain higher will display more detail from weak echoes, like fish, but will loose detail from the strong echo from the bottom. Fish recognition The echo strengths shown on the A-scope can be useful in recognizing the type of fish. Different species of fish have different sizes and shapes of swim bladders. The air in the swim bladder reflects the ultrasonic pulse, so the strength of the echo varies between fish species according to the size and shape of the swim bladder. When catching fish from a school, note the species and the strength of the echo that it returns on the A scope. Then, when that particular echo is seen again, it is likely to be the same fish species. Bottom type The shape of the echo strengths in the A-Scope can help you to recognise the type of bottom. 48 Simrad NX40/45 Installation and Operation Manual

51 13 Fuel functions and display The Fuel functions require optional petrol/gasoline or SmartCraft fuel sensors to be installed and set up What the fuel computer does Each engine has a flow sensor installed to measure the engine s fuel flow. The NX40/45 use these flows, together with boat speed and engine RPM if available to estimate the fuel remaining in the tank(s), fuel used, range and fuel economy. This data is shown on the fuel display. You can: display the fuel used during a trip. set low fuel alarms. make fuel consumption curves - graphs of fuel consumption and boat speed as a function of engine RPM - to monitor and optimize boat performance Fuel display To go to the Fuel display > More > Fuel The display differs according to the number of engines and tanks. To switch between a Summary or a Fuel curve display! WARNING To ensure the fuel data is accurate: When you add or remove fuel from a tank, tell the NX40/45. If the boat has petrol/ gasoline sensors, calibrate them during installation or if the fuel readings seem inaccurate. Choose an appropriate type of boat speed sensor to calculate economy, range and the fuel consumption curve. If the boat uses a paddlewheel sensor to measure speed, calibrate it during installation or if the speed readings seem inaccurate. If engine RPM is available and if you have made and selected a Fuel Consumption Curve. The Fuel display shows: Speed RPM (if available) If engine RPM is not available, the display shows depth. Remaining The fuel remaining in the tank(s) is shown as a vertical gauge on the right of the display. The height of the yellow bar(s) show how much fuel remains in the tank(s). If you have set a low fuel alarm, a red bar shows the level at which the alarm will trigger. If there are two tanks, the left bar shows the port tank, the right bar shows the starboard tank.

Note: If you follow procedure B every time you add fuel, then a small error will accumulate, because it is hard to measure exactly how much fuel you add. To avoid this, completely fill the tank and follow procedure A about every tenth time you add fuel. C - Removing fuel Before removing fuel > Set remaining On a multi-tank boat, select the tank that you are removing fuel from. Write down the value of Remaining for the tank; this is the amount of fuel originally in the tank. Remove fuel from the tank and write down how much fuel you remove.

55 Water speed and ground speed A paddlewheel sensor and a pitot sensor measure water speed, the boat speed through the water. A GPS measures ground speed, the boat speed over the bottom of the water. If there is a current, then these speeds will be different, and the log, trip log, economy and range will be different, as shown below. Water speed is better for measuring the boat s potential performance, Ground speed is better for going to a destination because it takes currents into account. When the current is from ahead, ground speed is less than water speed. For Example 1 If the boat travels for one hour, uses 3 gallons of fuel per hour and has 50 gallons of fuel left: When the current is from behind, ground speed is more than water speed. Example 1: A (water speed) = 10 knts. B (current) = 4 knts. Gives a ground speed of 6 knots. Example 2: Using water speed Using ground speed Speed Log Economy Range 10 knts 10 nm 3.3 nm/gal 165 nm 6 knts 6 nm 2.0 nm/gal 100 nm A (water speed) = 10 knts. B (current) = 4 knts at 45º. Gives a ground speed of about 8 knts. For Example 3 Using water speed Using ground speed Speed Log Economy Range 10 knts 10 nm 3.3 nm/gal 165 nm 14 knts 14 nm 4.7 nm/gal 235 nm If the boat travels for one hour, uses 3 gallons of fuel and has 50 gallons of fuel left: 13-6 Fuel consumption curves A fuel consumption curve shows fuel consumption (fuel used per unit of distance travelled) and boat speed as a function of engine RPM. Fuel consumption curves require engine RPM, which requires SmartCraft to be installed. Fuel consumption curves are powerful tools for assessing boat performance in different conditions and for helping you to run at the most economical speed for the conditions Making a fuel consumption curve To make a fuel consumption curve you will need to run the boat in a straight line for about 15 minutes using the engine s full RPM range. For your first curve, choose a calm day with light wind and little current; have a typical load and a freshly cleaned hull. Later, you can make fuel Example 3: A (water speed) = 10 knts. B (current) = 4 knts. Gives a ground speed of 14 knots. Example 4: A (water speed) = 10 knts. B (current) = 4 knts at 45º. Gives a ground speed of about 13 knts.

56 consumption curves for different boat, weather or sea conditions. Compare these with your first curve to see how your boat s performance changes with conditions. Making a curve Start running the boat in a straight line. Choose a speed source for the curve. Normally choose Water speed to measure the boat s potential performance. Press twice, then select Fuel. Select Fuel consumption curve, then select New. Enter the comfortable maximum RPM you know you can achieve for the engine rather than the maker s value. The NX40/45 then asks you to set the minimum RPM. Set the throttle to idle; on a multi engine boat set all engines to about the same idle RPM. Now, do not change the engine speed. Wait for about 60 seconds for the boat to stabilise, then press. Wait while the fuel computer records the data. The NX40/45 then asks you to set the throttle to achieve a target RPM. On a multi engine boat set all engines to about the target RPM. When the engine RPMs are correct, the Target RPM box will turn green. Now, do not change the engine speed. Wait for about 60 seconds for the boat to stabilise, ensuring the Target RPM box stays green. Then press. Wait while the fuel computer records the data. The NX40/45 repeats the above step to record data up to the maximum RPM. Then the NX40/45 asks if you want to save the curve. Select Yes. The fuel computer asks for a name for the curve.

D Blue curve: fuel consumption at different RPMs recorded when you made this fuel consumption curve. A C B E Blue marker: the fuel consumption now. This marker is below the blue curve, showing that the fuel consumption now at this RPM is better than when you recorded the curve. F If the blue curve has a dip, then running the boat at this RPM will give the best speed for the least fuel consumption. Simrad NX40/45 Installation and Operation Manual 57

58 13-7 Calibration Calibrate petrol/gasoline fuel flow sensors during installation, or if the fuel readings seem inaccurate and the other troubleshooting suggestions do not help (see Appendix B troubleshooting). Note SmartCraft fuel sensors are factory calibrated and should never need recalibrating. On a multi engine boat, calibrate each engine s sensor. This can be done at the same time with a portable tank for each engine or at different times using one portable tank. Calibrating a sensor requires accurate measurement of the fuel consumption. This is best done using a small portable tank. At least 4 gallons (15 litres) of fuel should be used to ensure an accurate calibration. It is often very difficult to fill underfloor tanks to the same level twice due to air pockets, so the more fuel used, the more accurate the calibration. To calibrate the sensor(s) Record the level of the fuel in the tank(s). Connect the portable tank(s) to the engine through the fuel sensor(s). Run the engine at normal cruising speed until at least 4 gallons (15 litres) of fuel has been used per engine. Check the actual amount of fuel used per engine by refilling the portable tank(s) to the original level and noting the reading(s) of the fuel dispenser s gauge. > > Fuel > Setup engines On a single engine boat, select Calibrate and change the shown value to be equal to the reading of the fuel dispenser s gauge, then press. On a multi-engine boat select the engine. Select Calibrate and change the shown value to be equal to the reading of the fuel dispenser s gauge, then press. Repeat for the other engines. 58 Simrad NX40/45 Installation and Operation Manual

62 16 AIS AIS is short for Automatic Identification System. The International Convention for Safety of Life At Sea (SOLAS) requires all vessels greater than 300 tons and all passenger vessels to be equipped with AIS Transponders. All vessels equipped with AIS permanently broadcast via one or more of the two dedicated VHF channels. This transmission may include information about the vessels MMSI-number, its call sign, name, position, course, heading, speed, rate of turn and type of vessel. This unit can receive and display AIS information when connected to an AIS receiver. Available AIS vessels transmitting in the local area are shown on the chart when this feature is enabled. We recommend the Simrad AI50 for the NX40/45. The following AIS receivers are also supported by this unit: Comar SLR200 (external GPS) Weatherdock Two Channel AIS Receiver NASA Marine AIS Engine 2 channel Receiver (external GPS).

65 17 Radar Radar is the Radio Detection And Ranging system. Radar functions require an optional Simrad radar system to be installed. Three radar systems are available; 2 kw, 4 kw, or 6 kw. When the radar is operating, the scanner transmits powerful microwave radio pulses which are reflected back from any solid objects such as land masses or other boats. These objects are called targets and are shown on the radar window. The scanner rotates through 360 so the radar window shows all of the area around your boat within the range of the scanner, producing a map-like display called the PPI (Plan Position Indicator). Typically, your boat is in the center of the radar window with concentric range rings surrounding it. The range rings help you to quickly estimate the distance to various targets Radar window The radar window shows: A K B C D G H I J L M E F A Distance between each range ring (in this example, 1/8 nautical mile) B Range of radar (in this example, shown in large digits) C Radar rotation (in this example, North Up) D Radar motion mode (in this example, Relative Mode) E Cursor F Distance and bearing to the cursor position G Compass ring H Range ring I North line (blue) J Heading line (white) K The bearing (in Relative, True, or Magnetic mode) L Echo Expansion setting M Interference Rejection setting Simrad NX40/45 Installation and Operation Manual 65

66 17-2 Radar modes There are four radar modes: Disabled. This saves on power consumption and magnetron usage. If the radar is disabled, it has to warm up and enter standby mode before it can start transmitting. Warming. The radar on and is warming up. This can take up to 90 seconds, depending on your scanner type. Standby. The radar is on and is warmed up. It is ready to start transmitting immediately. Transmitting. The radar is actively sending and receiving microwave radio pulses. An open array will be rotating. If you want to save on power but be able to start transmitting immediately, use standby mode Enabling the radar functionality When the radar is enabled, it will turn on, warm up, and enter standby mode. To enable the radar functionality > System Set Radar to. The radar immediately turns on and enters warm-up mode. A message shows how long this will take. When the warm-up period is complete, the radar enters standby mode and is ready to transmit Selecting standby mode or transmit mode > Transmit or (standby mode) 17-5 Disabling the radar functionality > System Set Radar to. A warning message appears. If you are sure that you want to disable the radar functionality, select Yes. 66 Simrad NX40/45 Installation and Operation Manual

67 The radar enters disabled mode immediately Adjusting the quality of the radar window Common problems that can degrade the quality of the radar window include: sea clutter rain clutter false echoes (sometimes called ghost echoes) and background noise side lobe patterns (false echoes that appear as an arc or a broken arc) shadows (blind spots) multiple echoes off the same object incorrect threshold setting If the radar is installed at a suitable height and in a suitable location on your boat, side lobe patterns and shadows (blind spots) caused by obstructions such as funnels or masts will be minimized. If you re having problems with these, you may need to relocate the radar. Consult the Installation Guide for your Simrad radar or talk to your dealer or installer. Multiple echoes off the same object are most likely to occur when you are close to a large target and are usually only a temporary nuisance. You can adjust the radar to reduce the effects of sea clutter, rain clutter, and interference from other radars. You can also change the gain mode setting and the gain level setting to help reduce false echoes. To adjust the radar > Presentation > Adjust Radar > Changing the gain mode Use the radar gain mode to specify whether you want to adjust the radar gain yourself or have it adjusted automatically. To change the radar gain mode > Adjust Radar > Gain Mode Simrad NX40/45 Installation and Operation Manual 67

68 Manual. Adjust the radar gain yourself to suit your local conditions and preferences. Auto. The radar gain is adjusted automatically Changing the gain level Use the radar gain level to adjust the sensitivity of the radar receiver. Ideally, the radar gain level should be set so that background noise is just visible on the radar window. If the radar gain level is too low, weak echoes won t be shown. If the radar gain level is too high, strong echoes will be difficult to see amongst the large amount of background noise. (If the radar Gain Mode is set to Auto and you adjust the gain level manually, the Gain Mode is changed to Manual.) To change the radar gain level > Adjust Radar > Gain Level > Changing the sea clutter mode (Manual mode) Sea clutter usually appears as confusing, random signals close to your boat on the radar window. High waves that can reflect the radar signal will produce the maximum amount of sea clutter. You can change the sea clutter mode yourself or have it changed automatically to compensate for the sea conditions. To change the sea clutter mode > Adjust Radar > Sea Clutter Manual. Adjust the sea clutter setting yourself. Harbour. The sea clutter setting is adjusted automatically to suit a harbour environment. Offshore. The sea clutter setting is adjusted automatically to suit an offshore environment. Range Rider. Adjust the sea clutter setting yourself for a particular radar range, then have those settings stored and automatically re-used whenever you operate at that range again Changing the sea clutter level If the sea clutter level is set too low, a lot of sea clutter will be shown. If the sea clutter level is set too high, 68 Simrad NX40/45 Installation and Operation Manual

69 small targets may not be shown in the radar window. If the sea clutter mode is set to Harbour or Offshore, and you adjust the sea clutter level manually, the sea clutter mode changes to Manual. If you are in Range Rider mode when you adjust the sea clutter level, the sea clutter mode does not change to manual but the setting is stored and used automatically whenever you use the same range again. To change the sea clutter level > Adjust Radar > Sea Clutter Level > Changing the rain clutter Rain clutter consists of random dots that can merge into badly-defined echoes on your radar screen. The random signals are returned from rain, hail, sleet, or snow and can result in a confusing display. If the rain clutter is set too low, there will be excessive rain clutter shown whenever it s raining. If the rain clutter is set too high, very large targets such as the coastline will appear to be hollow. To change the rain clutter setting > Adjust Radar > Rain clutter > Changing the threshold level Use this to define the threshold level of the weakest echo that you want to show on the radar screen. The threshold level is shown as a percentage. 100% is the maximum threshold level, meaning that only the strongest echoes are shown. 0% is the minimum threshold level, meaning that all echoes are shown. To change the threshold level > Presentation > Threshold > 17-7 Changing the echo expansion setting If you have several small targets in view and want to make them easier to see, use the echo expansion option. Note that the resolution decreases as the target size increases, so use this option only when target detection and visibility is more important that the quality of the display. Simrad NX40/45 Installation and Operation Manual 69

70 To change the echo expansion setting > Presentation > Echo Expansion Off. No echo expansion. 1. Targets expanded x Targets expanded x Turning the target trails on or off If you turn the target trails on, each target leaves a 30 second trail on the radar screen. You cannot change the length of the target trail. If you turn the target trails off, the targets do not leave trails. Note that if the radar motion mode is set to true, stationary targets won t leave a trail. If the radar motion mode is relative, any target that is moving relative to your boat will leave a trail. To change the target trails setting > Presentation Set the Target trails option to (target trails are on) or (target trails are off) Using the VRM/EBL Use one, or both of the VRM/EBL (Variable Range Markers/Electronic Bearing Lines) to quickly find the precise range and bearing of a target. A VRM can be fixed or floating. Use the VRM to find the range (distance) to the target. A fixed VRM is shown as a thin, dashed, circle centerd around your boat. Use this to find the distance of a target from your boat. You can move the center of the VRM away from your boat; for example, to measure the distance between two islands. This is called a floating VRM. The EBL is shown as a thin, dashed line extending from the center of the VRM to the edge of the radar window. Use the EBL to find the bearing of the target. To show EBL > VRM/EBL 70 Simrad NX40/45 Installation and Operation Manual

This is shown in a different pattern Changing the PPI position You can move the PPI (Plan Position Indicator) center to a different location if you are in Relative motion mode. (If you are in True motion mode, the radar automatically positions the PPI center.) To change the PPI position: From the radar window, press MENU then select Position. There are three choices: i Center. The PPI center is in the center of the radar window so that all other objects move relative to your boat. 72 Simrad NX40/45 Installation and Operation Manual

73 ii Look Ahead. The PPI center is positioned so that the radar window is offset from the center to give you the maximum view ahead. Set. Offset the PPI center in the radar window. (This works only when you are using relative motion (RM) mode). Use the arrow keys to move the PPI center to the new position then press to confirm. The new position must allow most of the radar sweep to appear on the radar window; if it doesn t, the PPI center will be moved as close as possible to the desired position Using the radar guard zones Use either or both of the two radar guard zones and alarms to notify you when a target enters or exits a specified area around your boat.

Rotation Palette Map datum The options for chart rotation are: North up North is always at the top of the chart window. Track up The chart is rotated so that the boat direction is to the top of the window. This option is useful for navigating narrow harbours or rivers. The unit asks for a course deviation resolution; this is how much the boat direction needs to change to make the chart redraw. Tip: If the chart redraws too frequently, increase the course deviation setting. Course up This option is only available if the boat is navigating to a destination. The chart is rotated so that the plotted course to the destination is vertical. Select the color scheme for the LCD window. The options are: Normal Sunlight Brighter colors, more visible in sunlight. Night Reversed colors for night, to preserve night vision. GPS positions are based on a worldwide reference (datum) known as WGS 84. Most paper charts are based on WGS 84. However, some paper charts are based on other datums In these cases, the latitude and longitude coordinates of objects on the unit chart window are different to the latitude and longitude coordinates of these objects on the paper chart. This applies to all objects, such as the boat, waypoints, tracks, lines of latitude and longitude! WARNING When you change to a chart with a different datum, change the unit map datum again. Simrad NX40/45 Installation and Operation Manual 77

78 Setting map datum and cartographic features such as land, rocks, buoys and depth contours. Use Map datum to select the unit map datum to match the datum of the paper chart. Then, the latitude and longitude coordinates of objects shown on the unit will change to match the corresponding coordinates on the paper chart. In the Chart setup menu > Map datum > Select the map datum for the paper chart you are using.! WARNING Map shift is for eliminating minor offsets. It should not be used if the correct datum is available. Use map shift with caution: incorrect application will cause incorrect boat positions. If you select a datum other than WGS 84 the unit asks if you want to apply the NMEA datum offset (see below). NMEA datum offset If you select a map datum other than WGS 84, the map datum offset can be applied to latitude and longitude coordinates sent on the unit s NMEA output: Map shift Latitude and longitude coordinates shown on any NMEA repeater do not match the coordinates on the unit. Latitude and longitude coordinates broadcast on any NMEA VHF transmitter will be the same as the coordinates on a WGS 84 chart. Latitude and longitude coordinates shown on any NMEA repeaters match the coordinates on the unit. However, latitude and longitude coordinates broadcast on any NMEA VHF transmitter will be slightly offset from coordinates on a WGS 84 chart. Some charts have consistent position errors. To correct this, apply a map shift. After a map shift: The positions of cartographic features (such as land, rocks, buoys and depth contours) move on the chart window to where they should be. The positions of the boat, waypoints, tracks, and lines of latitude and longitude on the unit chart window remain unchanged. 78 Simrad NX40/45 Installation and Operation Manual

Scroll speed Use this to set the scroll speed on the display. There is a choice of: Very Fast, Fast, Medium, Slow and Pause. The depth of the water also affects the speed of the display. Faster scroll speeds combined with a slow boat speed (typically between 2 and 6 knots) shows the most fish detail. Medium or Slow scroll speeds result in echosounder information being shown over a longer period, but with less detail. Fish depth labels When this is turned on, the depth of a fish is printed next to the fish arch. Digit size Use this to remove or change the size of the depth window on the echosounder windows. There is a choice of: Small, Medium and Large. Palette Use this to select a color palette. Each color within the palette represents a different echo strength, as shown on the echosounder windows. There is a choice of five color palettes: Black, Blue, White, Vivid and 8 color. The first four palettes display more detail, and each color covers a 1.5 db signal range. The 8 color palette displays less detail, and each color covers a 3 db signal range. Interference filter No filter, normal setting. Noise filter Filters the echo signal to remove spiky interference such as engine noise or echosounders on nearby boats. Averages the echo signal to remove rapid changes. Select Medium or High to give a smoother bottom trace this may help to detect a deeper bottom; Simrad NX40/45 Installation and Operation Manual 81

82 however these settings may also remove fish echoes. Select Off for best fishfinding. Surface clutter filter Use this filter to hide the surface noise. Any significant echoes (such as fish) will still be shown. Pulse length This can be used to specify the length of the transmitted ultrasonic pulse. A short pulse length improves the window detail but contains less energy, therefore it does not penetrate as deeply into the water as a longer pulse. There is a choice of Auto, Short, Medium or Long. The Auto setting is recommended. Pulse power This can be used to specify the power output of the transmitted ultrasonic pulse. Low power output conserves the battery and produces a clear display in shallow water. There is a choice of Auto, Low, Medium or High. The Auto setting is recommended Setup > Radar > Radar Note: This option is shown only when the radar is enabled. Rotation The current radar rotation is shown in the top left corner of the radar screen. If COG data or heading data is not available from a compass, the radar rotation is automatically set to Head up. If heading data is available from a compass, the options are: North up works only when COG data or heading data from a heading sensor is available. North is always at the top of the radar screen. Head up means that the radar image rotates underneath your boat, so the direction in which you are heading is pointing to the top of the radar screen. You can easily compare the visual view in front of your boat with the radar screen. Course up works only when COG data or heading data from a heading sensor is available and there is an active route. It means that your 82 Simrad NX40/45 Installation and Operation Manual

83 desired heading is always pointing to the top of the radar screen so that you can compare the leg bearing of the active route with the radar screen. (If you re in Course up rotation but don t have an active route, the radar uses Head up rotation until a route is made active.) Motion mode True motion mode is not available if there is no position data, and no heading or COG data. There are two choices: Relative (RM). Your boat remains in a fixed location on the radar screen and all other objects move relative to your position. (You can choose the position of the fixed location). RM is the default. True (TM). Your boat, and moving targets, move across the radar screen as you travel. All stationary objects remain in a fixed position. You must have position data, and heading or COG data for this option to be available. Interference filter If the radar on another boat is operating at the same frequency as your radar, it can cause interference patterns on the radar window. Interference patterns always appear in a different place with each sweep. They can be randomly scattered bright dots or dotted lines that extend from the center to the edge of the radar window, often producing a spiral pattern. Generally, the stronger the interference, the wider the interference lines. Use the interference rejection option to reduce both the interference patterns and the width of the interference lines.

You can show this information in small, medium or large digits. The range rings and compass ring help you to quickly estimate the range and bearing of a target from your boat. The range ring and compass ring are shown. The number of range rings and the spacing interval between them is set automatically according to the range setting. The current spacing interval is shown in the top left corner of the radar window. Range ring and compass ring are hidden. Whatever the radar window rotation, you can always show the blue North line.

Hide the heading line Setup > Radar > Installation > Radar > Installation Note: This option is shown only when the radar is enabled. Park position If your radar has an open array and you take it out of enabled mode, the open array continues to rotate for a short distance before it finally stops. The stop position is known as the park position. You can adjust the angle of the parking position so that the open array will always stop at 84 Simrad NX40/45 Installation and Operation Manual

85 Zero bearing Zero range your preferred position; for example, facing the bow. Select Park position then enter the angle of the new park position. Note: You may need to try a few different park positions to find the correct one. The strength of the wind will also affect the park position. Use the zero bearing alignment to rotate the radar image, one degree at a time, so that a known object dead ahead is directly under the boat s heading marker. This means that the radar image is aligned with the shown chart and the compass. An accurate bearing alignment is particularly important when the radar image is overlaid onto the chart. Adjust this on a chart window with the radar overlay on. Select Zero bearing then use the cursor to enter the new bearing angle. The zero range is also known as the radar range offset and as the trigger delay. If your radar window shows a blank, black circle around the center or a solid circle of color at the center, you need to adjust the zero range setting until this circle disappears or almost disappears. Ideally, the radar sweep should start at your boat (a radar range of zero).! WARNING Fuel consumption can change drastically depending upon the boat loading and the sea conditions. Always carry adequate fuel for the journey, plus a reserve. To adjust the zero range setting: Position your boat about 45 to 90 m (50 to 100 yards) away from and parallel to a straight-walled jetty or similar feature. Adjust the gain setting if necessary, so that a reasonably good image of the jetty echo is shown on the radar window. At this stage, the jetty echo may appear to be bent. Select Zero range then use the arrow keys to adjust the zero range setting until the jetty echo appears as a straight line on the radar window. Antenna height The Installation Manual for your Simrad radar explains how to find the optimum height for your radar scanner (antenna). Simrad NX40/45 Installation and Operation Manual 85

86 18-5 Setup > GPS > GPS Select Antenna height then enter the height of the antenna above sea level. GPS Source Static Navigation Speed and Course Filter 18-6 Setup > Fuel > Fuel SimNet: Use the GPS source via SimNet (GPS port) NMEA: Use the external NMEA 0183 GPS antenna (Fuel/Nav port). When the boat stops or moves very slowly, the calculated GPS speed and course become erratic. Static navigation allows the erratic values to be filtered: 0.01 to 9.99: If the boat speed is slower than this, the speed is shown as zero and the course stays unchanged. 0 (Off): The calculated speed and course are always used. Waves and wind cause the boat speed and course to fluctuate slightly. To give stable readings, the unit calculates these values by taking several measurements and averaging them. A lower value averages measurements over a shorter period of time. This gives the most accurate value but has the most fluctuations. Note: Fuel functions require fuel flow sensors to be installed. Source Num engines Num tanks Select the fuel flow sensors to use if the boat has more than one set of fuel sensors. Normally select Auto. Set the number of engines, or select 0 to disable the fuel functions. If there are two engines they are called port and starboard. Set the number of fuel tanks. If there are two tanks they are called port and starboard. 86 Simrad NX40/45 Installation and Operation Manual

87 Setup engines If the boat has more than one engine, select Engine and select each engine in turn. For the selected engine, enter: From tank: The tank the engine is connected to. Flow filter: Most engines do not draw fuel from the tank at a steady rate. To give a stable fuel flow reading, the NX40/45 calculates the flow by taking several measurements and averaging them. Use the Flow filter to set the period over which the fuel flow is averaged. The Flow filter can be set from 0 to 30 seconds. Use the lowest value which gives a stable flow.usually a value of 5 to 10 seconds will give a satisfactory result for two-stroke carburetor engines. Fuel injected or four-stroke engines may require a larger value. This setting affects the Fuel flow and Fuel economy reading on the Fuel display but it does not affect the Fuel used reading. Setup tanks If the boat has more than one tank, select Tank and select each tank in turn. For the selected tank, you can enter: Tank size: The tank capacity.

Calibration may be required because different hull shapes have different flow characteristics. Note: for accurate calibration, The speed from a GPS receiver should be greater than 5 knots, and the speed from another paddlewheel transducer should be between 5 and 20 knots. Best results are achieved in calm conditions where there is minimal current (best at high or low tide). Calibrating speed Travel at a constant, known speed.

92 the unit calculates these values by taking several measurements and averaging them. Set the Speed filter to the lowest value which gives stable readings. The range is 1 to 30 seconds or Off (0). Temperature The factory settings should be sufficiently accurate for normal usage. To calibrate the temperature readout, first measure the water temperature with a thermometer known to be accurate. Use the cursor keys to display the temperature readout box, then increase or decrease the value to match the measured temperature. The temperature can be set from 32 to 99.9 F (0 to 37.7 C) with a resolution of 0.1 unit. To change the units between F (Fahrenheit) or C (Celsius). Temperature filter Water turbulence and currents cause the water temperature to fluctuate slightly. To give stable readings, the unit calculates these values by taking several measurements and averaging them. Set the Temperature filter to the lowest value which gives stable readings. The range is 1 to 30 seconds or Off (0). Keel Offset A depth transducer measures depths below where the transducer is mounted on the boat, usually the bottom of the boat. The unit calculates the depths to display by adding the keel offset to all measured depths. A Have a zero keel offset to display depths below the transducer. B Enter a positive keel offset to increase the shown depth. For example to display the total depths below the surface, enter the depth of the transducer below the surface. C Enter a negative keel offset to decrease the shown depth. For example, to display the depths of clear water below the boat, enter minus the depth of the deepest part 92 Simrad NX40/45 Installation and Operation Manual
